ABSTRACT:
A motorcycle boot has an upper wrap-around shell, closed by a buckle and strap, which overlaps a lower vamp shell having a plurality of forward and rear tapering fingers which extend into the upper shell to allow hinging movement of the upper shell. Flexible liners are inserted into the vamp to custom fit the vamp shell to a wearer's foot. An interconnecting hinge assembly includes a pivot pin, journalled in the upper shell, and slidably mounted within a slotted plate attached to the lower shell, to allow the upper shell to pivot forwardly and rearwardly and rock sideways. The base of the lower shell, with a steel plate embedded in the instep arch, is covered by a replaceable sole attached by adhesive which forms a rupturable seal. To waterproof the boot, a flexible cylindrical liner is sealed to the lower vamp and extends through the upper shell, with the liner top being folded down and externally attached to the upper shell.
